Polyaluminum chloride is a commonly used water purification agent product, but the polyaluminum chloride on the market can be divided into a variety types according to different raw materials, different processes and different functions, and the price and effect of different polyaluminum chloride also is different, so how can we choose suitable polyaluminum chloride products?

Here is a small case study on the selection and use of polyaluminium chloride. River water is a common water resource, but most of the river water contains a lot of sediment, resulting in river water pollution. At this time, polyaluminum chloride can be used to achieve the effect of decontamination and turbidity removal, but at this time, choosing the appropriate type of polyaluminum chloride can achieve better effect.

The price distinction of polyaluminium chloride in the market is mostly based on the content, in terms of type, there are spray dried PAC and roller dried PAC. When people buy polyaluminum chloride, they usually want to choose some polyaluminum chloride products with lower price and better effect.

In order to make the sediment in river water precipitate rapidly, low-end PAC products with a content of 20% or less are generally used instead of high price products with a content of 30%. This is mainly because the polyaluminum chloride with 20% content has more powerful coagulation and sedimentation effect on some large particles of sediment, especially when it is used with polyacrylamide, It greatly improves the purification efficiency of river water.

Therefore, when purchasing polyaluminum chloride, it is not that the more expensive the polyaluminum chloride is, the better the effect will be. We need to have an understanding of our own sewage treatment, and select the appropriate type of polyaluminum chloride according to the nature of sewage, so as to achieve good water purification effect.
